Which nails are most commonly affected by ingrown toenails?

Ingrown toenails most commonly occur in the large or "great toes." However, any of the toenails can be affected on either border or side.

What causes infections in ingrown toenails?

The warm, moist environment of the feet can be a breeding ground for bacteria and fungi. These commonly include
Staphylococcus, Pseudomonas, dermatophytes, Candida, and Trichophyton. When there is a break in the skin from the offending nail border, these organisms can invade the area and cause an infection. Treatment for these infections is essential to maintain healthy toenails and feet.
